Genetic structure of natural populations of the relict species Aristolochia manshuriensis (Aristolochiaceae) in disturbed and intact habitats

Genetic structure of natural populations of the relict species Aristolochia manshuriensis... Genetic structure of natural populations of the rare relict plant Manchurian birthwort (Aristolochia manshuriensis Kom.) in the Russian part of its area was analyzed using allozyme markers. The studied A. manshuriensis populations differed in the degree of their intrapopulation differentiation. The populations Nezhinka and Anan’evka were more differentiated (F ST = 0.1209 and 0.0576, respectively); these populations are located close in the regions of intense economic activity and are exposed to the strongest anthropogenic impact. A low degree of differentiation was detected in the population Malaya Borisovka (F ST = 0.0393), localized to intact habitats. The overall heterogeneity test has demonstrated that the population Malaya Anan’evka, exposed at present to small anthropogenic stress yet growing in disturbed habitats, displays no differentiation. These results suggest that at least three populations are influenced by genetic drift connected with a decrease in the reproductive and effective population sizes, which is caused, in particular, by anthropogenic impact. A high level of genetic similarity between the A. manshuriensis populations in Primor’e is discussed in connection with the evolutionary history of this species. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Genetics Springer Journals
